Filter design for discrete-time two-dimensional T–S fuzzy systems with finite Frequency Specification
International Journal of Systems Science, 2019Co-Authors: Zhaoxia Duan, Jun Zhou, Jian ShenAbstract:This paper deals with the filter design problem of two-dimensional (2-D) discrete-time nonlinear systems described by Fornasini–Marchesini local state–space (FM LSS) model under Takagi–Sugeno (T–S) fuzzy rules. The Frequency of disturbance input is assumed to be known and to reside in a finite Frequency (FF) range. A novel so-called FF l2 gain is defined for 2-D discrete-time systems, which extends the standard l2 gain. The aim of this paper is to design filters such that the filtering error system is asymptotically stable and has the disturbance attenuation performance in sense of FF l2 gain. Sufficient conditions for the existence of a desired fuzzy filter are established in terms of linear matrix inequalities (LMIs). Simulation examples demonstrate the technique and its advantage.

an achievability condition for n dimensional behaviors with a finite Frequency Specification dissipation inequalities approach
Conference on Decision and Control, 2010Co-Authors: Chiaki Kojima, Shinji HaraAbstract:Many of practical design Specifications are provided by finite Frequency properties described by inequalities over restricted finite Frequency intervals. The properties are known as the important property in integrated design of plant and controller. Recently, it was proved that the property is equivalent to the dissipation inequality in time and space domain, where the dissipation inequality is an inequality which describes the energy and power interaction of a dynamical system with its outside environment. In this paper, we consider a synthesis of a controller for finite Frequency properties for n-dimensional systems described by partial differential equations. As a main result, we derive a necessary and sufficient condition for the achievability of a controller satisfying a finite Frequency Specification in terms of dissipation inequalities. This result clarifies a physical interpretation of the controller from the dissipativity viewpoint.

Frequency Specification Testing of Analog Filters Using Wavelet Transform of Dynamic Supply Current
Journal of Electronic Testing, 2005Co-Authors: Swarup Bhunia, Arijit Raychowdhury, Kaushik RoyAbstract:Wavelet transform has the property of resolving signal in both time and Frequency unlike Fourier transform. In this work, we show that time-domain information obtained from wavelet analysis of supply current can be used to test the Frequency Specification of analog filters efficiently. The pole/zero locations in the Frequency response of analog filters shift due to change in component values with process variations. It is essential to test the filters for the shift in Frequency response and fix it during production test. Wavelet analysis of supply current can be a promising alternative to test Frequency Specification of analog filters, since it needs only one AC stimulus and is virtually unaffected by transistor threshold variation. Simulation results on two test circuits demonstrate that we can estimate pole/zero shift with less than 3% error using only one measurement, which requires about 18 measurements in the conventional technique.
